hi all
im in the proscess of changeing my sprockets and chain
i noticed on my my cush drive inserts or(whatever you call them)
they all have a very slight crack in the rubber section of the inserts
my 08 hyper has 15000 mi on it
my question is should i replace these with new ones or are the cracks normal wear and tear and reuse them
thanx in advance.......................wayne

I think you should replace them. Here is a link for new ones. They are at the bottom of the page.

Since you already have it apart that "light weight hub" looks nice too!

Cracked doesn't seem normal to me, I would replace them. Honestly surprised they lasted as long as they did since they are just cheap rubber.
